Thankfully, an M5 police car would likely never become reality in the U.S. where taxpayers would surely give their municipality hell for adding such an extravagant car to its fleet. Then again, Texas may be able to justify such a purchase thanks to highways christened with new 85-mph limits. Either way, the M5 inspired this list of the top 5 cop cars to come from automaker performance divisions. It’s a rare fantasy car list we hope never become reality.

2012 Mercedes-Benz E63 AMG Wagon

Here’s a wagon that’s just 0.2 seconds slower than the aforementioned M5. At the officer’s disposal is a hand-built, 550-hp, 5.5-liter twin-turbo V-8 and a ton of AMG goodies to ensure this wagon is agile enough for high-speed city chases (we achieved a lateral acceleration of 0.92 g). And not only is it quick, it’s practical, too, thanks to its huge ammo-hauling trunk.

2012 Ford F-150 SVT Raptor

If you’ve ever watched the show “COPS,” you’re likely familiar with runaway suspects who can’t seem to keep their car on the road. Catching those pesky perps would be a breeze in a Raptor. In fact, this is the only car on our list that is actually used by American law enforcement. The U.S. Border Patrol depends on a fleet of Raptors to traverse rough and sketchy terrain. And the truck is certainly up to the task thanks to an impressive list of hardware such as its 411-hp, 6.2-liter V-8, Fox Racing Shox, and locking differentials.

Cadillac CTS-V Wagon

If you agency favors a fleet of sleepers, the Caddy wagon may fit the bill. You’re probably familiar with the wagon that served as a Motor Trend long-termer, but just in case you’ve been living under a rock, let’s just say we loved it. In fact, we paired it again the E63 AMG wagon and it won. With a 6.2-liter supercharged V-8 rated at 556 hp, this is one car you don’t want to see in your rear-view mirror.

What car from an automaker’s performance division do you think would make an awesome cop car?

I'd dig finding a police supervisor's Plymouth Satellite or Dodge Coronet wagon from back in the day and stuffing the same 392 Hemi that's in the Grand Cherokee SRT-8 along with some modern suspension.
